Sveta, we are talking about 2 different things here AGAIN.
I am not saying that Russia is right to support Iran.. in fact from my standpoint they are acting like fucken assholes. However from *russia* perspective they are doing their best to counterposition themselves to US as a superpower they used to be.
But even that is not my point. My point is US does what's beneficial to US (thru the prism of whoever is in power) before anyone else, and Russia does what's beneficial to Russia.
This is why US supported and will support people who some other country may call terrorists and so will Russia..
